Math.sin()

The Math.sin() function returns the sine of a number.

Syntax

Math.sin(x)

Parameters

x
A number (given in radians).

Return value

The sine of the given number.

Description

The Math.sin() method returns a numeric value between -1 and 1, which represents the sine of the angle given in radians.

Because sin() is a static method of Math, you always use it as Math.sin(), rather than as a method of a Math object you created (Math is not a constructor).

Examples

Using Math.sin()

Math.sin(0);           // 0
Math.sin(1);           // 0.8414709848078965
Math.sin(Math.PI / 2); // 1
